Square hollow carbon tube has no actual dimension variants. The required legs, wall and length need a complete section drawing.

Define a feasible hollow section

Reference wall is0.4–16mm and lengths include6m,6.4m,12m or6–12m/customized. Specify actual bore, corners and wall rather than assuming all combinations are available.

• Square section.
• Carbon-steel grade field.
• Hot-rolled treatment.
• Non-oiled description.
• Cutting and bending services.

Select material and process

ASTM and API-related references need an applicable specification and actual grade record. No numerical strength or manufacturing-route test is supplied.

Agree service inspection

Oil, boiler and structural contexts do not establish pressure ratings, design capacity or approved installations. Request actual material, dimensional and weld/process tests before assigning the selected square tube to service.
